VaLSA (cALOSPORA) APATELA (o7rar;/A0f) EIUs & Hohvaj . 



Stroma cortical, orbicular, 2-3 mm, perithecia 6-10 subcir- 

 t>>^rUri./ cinating %-% "^1"^? their stout, rough, black conico-cylindric 

 } ^ "^ subtruncate and imperfectly quadrisulcate ostiola, about-=in 

 long diameter the perithecia, bursting through the bark in a 

 compact fascicle but scarcely rising above it. Asci oblong 

 fusoid or broad lanceolate, 75-80 X 14-16//. Paraphyses? 

 Sporidia irregularly crowded, fusoid, 4-nucleate, becoming 

 3 septate and slightly constricted at septa, h^-aline ends rather 

 -obtuse, 25-40x6 8//, mostly between 30 and 4O// long. 



The stroma though black outside seems to be composed 

 within of the scarcely altered substance of the bark. Cryptos- 

 ■pora caryce Pk. 



On dead hickory limb. Decorah Iowa, March, 1888. 



■Cercospora (Cercosporei.la ) PROLiFiCANs EIUs & Ilolway. 



Amphigenous, but more abundant on the lower side of the 

 leaf. Hyphai densely fasciculate, short, 25-30X4/Z, continu- 

 ous, hyaline; tufts effused forming subindefinite, suborbicular, 

 rufous-gray patches, 3-5 mm in diameter. Conidia clavate- 

 cylindrical, granular, hyaline, faintly 1-3-septate, 30-75x3-4//. 



This is quite distinct from C. depazcoidcs Desm. which has 

 longer hyphaj and is on definite dirty white spots.

FusiCLADiUM PEucEDANi ElUs & Holzuay. 



Amphigenous. forming abundant, small, olive-black spots, 

 resembling the sori of Piiccinia. Conidia oblong, slightly 

 narrower in the middle, ends obtusely rounded and the lower 

 end mostly a little narrower, olive-brown and minutely rough- 

 ened, terminal on olivaceous, continuous hyphai shorter than 

 the conidia.
